Summary: Plants regulate their growth and development through a complex interaction between nutrients and hormones, ensuring survival. Different forms of sugars and the hormone CKs play crucial roles throughout the plant lifecycle. However, there is still limited research on their combined effects, indicating a need for further exploration.

Summary: Source traits, such as photosynthesis, play a crucial role in enhancing crop yield potential. However, for a comprehensive understanding, the interactions of various processes in crop regulation, including sink activities, need to be considered. This review uses 'wiring diagrams' to integrate these interactions and examine the regulation of source traits at different stages of wheat development. The review also discusses challenges and opportunities in photosynthesis components due to canopy formation and the feedback regulation of source activity.

Summary: Striga hermonthica is the most important parasitic weed in sub-Saharan Africa and remains one of the most devastating biotic factors affecting sorghum production in the western regions of Kenya. This study aimed to identify new sources of resistance to Striga and evaluated 64 sorghum genotypes in field and pot trials, finding stable and high-yielding F-4 crosses as well as some genotypes and a check showing high resistance to Striga. Future research should focus on finding more diverse sources of Striga resistance and incorporating different resistance mechanisms into farmer-preferred varieties to enhance the durability of Striga resistance in the fields.

Summary: Photoperiod is crucial for plant flowering, and different plants have different responses to photoperiod. The molecular mechanisms of flowering time in rice and Arabidopsis have gradually been clarified, providing an opportunity to study the differences in day length measurement between these two types of plants. The relationship among photoperiodic regulators and a proposed regulatory framework for the reversible mechanism are evaluated, which deepens our understanding of the CDL regulation mechanism.

Summary: This study analyzed the leaf transcriptomes of strong and weak hybrid plants and their parents, and found differentially expressed genes related to plant hormone signaling and photosynthesis pathways, as well as genes related to cell size. The results suggest that these pathways play a role in regulating the dynamic changes and heterosis in hybrid plants.

Summary: Intraspecific hybrids of Arabidopsis sometimes exhibit heterosis, although allelic variation of flowering repressor genes results in late flowering in F-1, potentially distorting the heterosis effect due to prolonged vegetative growth. In this study, overexpressing the flowering gene FT synchronized flowering and minimized growth differentials between parental and F-1 plants. These findings indicate the potential for quantitatively demonstrating the inherent heterosis caused by heterozygosity.

Summary: This research aimed to evaluate the agronomic performance of sorghum hybrids under different drought stress conditions and identify hybrids tolerant to drought stress and responsive to water supply. The study found that certain hybrids performed well in terms of yield and earliness under different drought stress conditions, making them suitable for different crop seasons.

Summary: Efforts to enrich the varietal wealth in litchi with desired cultivars have been attempted, but there are several hurdles such as low genetic variability, short flowering period, small flowers, high flower and fruit drop, and low seed germination. Strategies need to be devised to address these issues.

Summary: Matching flowering time to the optimal period is crucial for maximizing yield in Mediterranean cropping zones. Plant hormonal products, particularly gibberellin (GA), have shown potential for altering development and delaying flowering in barley. Trinexapac-ethyl, a GA inhibitor, was able to delay flowering and extend pre-anthesis phases of development in genetically diverse barley cultivars.

Summary: By utilizing the A3 cytoplasmic male sterility system, sweet sorghum hybrids can increase sugar yield and biomass accumulation. The A3 hybrids showed higher degrees Brix value, biomass, juice, and sugar yields compared to the A1 hybrids, and exhibited greater resistance to lodging.

Summary: This study investigated the functions of BdPIL1 and BdPIL3, two PIF-like genes in Brachypodium distachyon, and found that they interact with phytochromes in an active form-specific manner, affecting plant growth and development. Transgenic Brachypodium seedlings with RNAi constructs of BdPIL1 and BdPIL3 showed decreased coleoptile lengths, increased leaf growth, taller stature, and delayed flowering compared to wild-type plants, with downregulation of genes related to cell number regulation, floral induction, and chlorophyll biosynthesis. Additionally, the study revealed the DNA-binding ability of BdPIL1 and BdPIL3 to target promoters was inhibited in the presence of phytochromes, providing insights into the molecular mechanism underlying phytochrome-mediated PIF regulation in Brachypodium.

Summary: This study evaluated the genetic variation of plant height and total soluble solids in P. angulata through a full diallel design with five accessions. Several hybrids were identified as the best performers based on selection indexes, exhibiting shorter plant height and higher total soluble solids. This is the first report of heterosis and heterobeltiosis in P. angulata descriptors using diallel analysis.
